Application and 1.,- 22. 1905. Serial No. 261.5 74.

In all whom it may concern:

Beit known that I, WILLIAME. HART, a

- residentof Greatbend,inthecountyofBarton and State of Kansas, have invented certain new and useful Improvements in Fly-Screens; and I do hereb declare thefollowing to be a full, clear, an exact description of the in'--' vention, such as will enable others skilled in light on the inside thereof to escape to the outside and prevent any possibilityof their return by the same route; and the invention consists in certain novel features of construcion and combinations and arrangements of zo' 'parts, as will be more fully heremafterdescribed, and pointed out in the claims.

the accompanying drawings, Figurel is a viewin elevation, illustrating my improvements. Fig; 2 is aview in vertical section, and Fig. 3 is a view-of the'outlet-tube re-; moved.

' 1 represents the screen-frame, which may be of any material, shape, and construction to suit conditions of its use, having a wirenetting 2 secured edges "provided with strips 3 to overlie and confine the edges of the wire-netting. In

'the upper portion of the screen-frame inj clined ars 4 are secured and are joined at the center of the top vbar. A short wire-netting apron 5 is secured to the inner face of the frame '1 against bars 4, and as the bars 4 are of the proper thickness or width to snugly fit between the outer netting 2 and inner a ron 5 flies walking up the screen are directe by the incli ed bars 4 to the central upper portion of the-screen, where my improved outlet from the outside,

spout or tube 6 is located, and will now be described in detail. I

The tube 6 is of wire-netting having ltsouter end ragged to prevent entrance therein and the inner end of the tube is secured about the centrally-coiled portion of a wire 7. The ends of the wire 7 are-secured to bars 4, and the wire holds the tube 6 properly in the opening in screen, so as to rovide easy entrance there'lnto from the insi e for the flies which walk to the upper end of the screen.

to 'oneface and having its tween said screens at the lower en onal bars secured to the and secured to the uide-bars,

As is well known, when flies light .upon a I screen or other device they always walk in an upward; direction, and with my improvements the flies pass into the'space behind apron 5, and when they find that they cannot fly backward into the room they will coninue their upward course and, guided bybars 4, will see the outlet through tube'6 and will enter and escape 5,'netting 2, and bars 4 form, in effect, a trap from which the only outlet for flies is thi'ou h the tube 6, as the flies rarely if ever w down a screen. My to a screen afford perfect escape for the 'flies without sacrificing the air-circulatin space in the slightest, as the air can free pass through the/screen above bars 4 as welYas below them.

Slight changes might be made'in the gen eral scribed without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself 'mprovements applied therethrough. The apron orm and arrangement of the parts deat liberty to make such slight changes and alterations as fairly fall within the spirit and scope of m invention.

Having lly describ ed my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination with a frame, of two screens secured thereto and spaced apart, one

of. said screens shorter than the .other and leaving an unobstructed inlet to the s acebeing witnesses.
